Here are my own versions and redesigns of the Student 6. Yona has already been drawn out and here's the picture in case you haven't seen it yet.

They all comprise of each of the major species in Equestria: a yak, changeling, hippogriff, griffon, dragon, and pony.

All of the Student Six are adults with the exception of Smolder who will remain a teenager for the sake of having a little sister type in the group and for creating comical situations.

Each of them either will retain their original personalities or have drastically different personalities, Sandbar being one of them. He's seen in the show as more kind-hearted and casual, but in this version he's a weight-lifting bro with a cool and tough personality. Remember that I'm doing an alternate Equestria all inspired by the episode where Starlight forced Twilight into different realities parallel to theirs so she could rewrite their fate. Most of the events still played out from the canon universe, but with many alterations with how they ended.
